Businesses, manufacturers, wholesalers and retailers can easily calculate GST using this formula:
               
               Simple GST calculation
               • Add GST:
               GST amount = (Original cost x GST%)/100
               Net price = original cost + GST amount
               
               • Remove GST:
               GST amount = Original cost - [Original cost x {100/(100+GST%)}]
               Net price = Original cost - GST amount
               
               Here’s an example to illustrate this:
            
| Rate (%) | Amount | |
|---|---|---|
| Original cost of goods | Rs.1,00,000 | |
| GST | 18% | Rs.18,000 | 
| Cost of goods sold | Rs.1,18,000 | 
| Rate (%) | Pre- GST | Post- GST | |
|---|---|---|---|
| Cost of product | 10000 | 10000 | |
| Excise duty | 12% | 1200 | Nil | 
| Profit | 10% | 1000 | 1000 | 
| TOTAL | 12200 | 11000 | |
| VAT | 12.50% | 1525 | Nil | 
| CGST | 6% | Nil | 660 | 
| SGST | 6% | Nil | 660 | 
| Final invoice to the wholesaler | 13725 | 12320 | 
At a cost point of Rs.10,000, the manufacturer is saving Rs.1405 i.e. a 14% tax saving on the cost. This brings a cost reduction for manufacturers, the benefit of which is ultimately passed on to the wholesalers, retailers and consumers.
                
            
| Rate (%) | Pre- GST | Post- GST | |
|---|---|---|---|
| Cost of product | 13725 | 12320 | |
| Profit | 10% | 1373 | 1232 | 
| TOTAL | 15098 | 13552 | |
| VAT | 12.50% | 1887 | Nil | 
| CGST | 6% | Nil | 813 | 
| SGST | 6% | Nil | 813 | 
| Final invoice to the consumer | 16985 | 15178 | 
GST brings down the cost of the product and thus, the consumer pays a lesser price for the goods at the same profit% earned by wholesalers and retailers.
